AROMATIC BLISTER PACKAGE Filed Feb. 5, 1963 FIG. 4 IN TOR 150M420 ,4 V/n Q United States Patent 3,249,217 AROMATIC BLISTER PACKAGE Leonard A.'Irving, Baltimore, Md., assignor to Marlenn Products Company, Inc., Baltimore, Md., a corporation of Maryland Filed Feb. 5, 1963, Ser. No. 256,306 6 Claims. (Cl. 20678) a certain scent on the same and then to utilize the figure for both a decorative and a fragrant effect.

Such use, however, has been limited by the costly packaging necessary for such items and the lack of pleasant visual appearance of the finished package.

It is a cardinal object, therefore, of this invention to provide a new and improved package for decorative and scented items.

Another object hereof is the provision of a more economical novelty package that may be conveniently massproduced.

' A still further purpose and accomplishment hereof is the provision of a display package that will retain the scent of an aromatic item therein.

The above objects and accomplishments are obtained by providing a package of the bubble or blister type with a metalized backing on a cardboard or paperboard base.

With these objects in view, the invention consists of the novel features of construction and arrangement of parts which will appear in the following specification and recited in the appended claims, reference being had to the accompanying drawings in which the same reference numerals indicate the same parts throughout the various figures and in which:

FIG. 1 is a fractional sectional elevational view of one step in the process of fabrication of the instant invention.

, FIG. 2 is a view corresponding to FIG. 1 but showing a further step thereof.

FIG. 3 is a view corresponding to FIG. 2 but showing a still further step thereof.

FIG. 4 is a-view -in perspective of one exemplary embodiment of the product produced according to this invention.

FIG. 5 is a sectional elevational view on an enlarged scale taken substantially along line 55 of FIG. 4.

FIG. 6 is a view in perspective of the backing member utilized in conjunction with the illustrated package.

Illustrated in FIGS. 1, 2 and 3 of the drawings is one primarily diagrammatic method of fabricating the product of this invention.

It will be noted that many of the steps and materials utilized are shown in their simplified form for ease of understanding and that commercially other well known steps may be added and substitutions made.

In FIG. 1, however, there is shown the cross section of an anvil 10 having an internal cavity 11 conforming to the shape of one portion of the finished package 12. The internal cavity 11, as will be seen hereinafter, is roughly in the shape of an inverted dome thereby forming a complete bubble member with one opening having laterally extending flanges 30. The flanges will form a surface, for ease of sealing to a backing memher, as will be set forth hereinafter.

Resting above the internal cavity 11 and on the anvil 10, will be a sheet 14 of suitable display package material. The said sheet 14 should preferably be transparent, heat sealable, and impervious to gas and vapor. On such material, for exampdle, would be a clear butyrate.

A die member 20 will be urged under pressure into the cavity 11 causing the heated sheet of material 14 to conform to the shape of the said internal cavity 11 as shown in FIG. 2. After the sheet 'of material 14 is so set, under pressure and most often heat, the die member 20 will be removed.

A novelty item 21, which may be of any well known, shape, will be impregnated with any well known scented, and/or deodorizing compound. This will permit the decorative item 21 to be utilized as an effective air deodorizer or the like. It will be necessary, however, to protect the said item in an impervious package to insure against the loss of scent While the said item is stored, transported, and otherwise until used.

For this purpose, the decorative item 21 is placed face down Within the now formed sheet of transparent material 14, as shown in FIG. 2. It is well known that materials such as clear butyrate will effectively block the loss of scent from an area surrounding the decorative item 21.

To block the escape of the fragrance from the open top of the now formed sheet of material 14, however, a strip of metal 24 die cut to the configuration of the opening from the formed sheet of butyrate 14, will be placed over the said opening illustrated at 26. The strip of metal 24 may, if desired, be replaced by a more economical material, with a coating of metal. Again, as is well known, such metal, or materials coated with metal, will be relatively impervious to any of the ordinary perfumes or other scented items.

The strip of metal 24 may be somewhat larger than the internal cross section of the formed sheet 14. Thus, as may be seen in FIGS. 2 and 3 and 6, it will be some- What compressed by the side walls of the said formed sheet 14 so as to create a tight seal between the metal- 24 and the sheet 14. This will prevent the communication and flow of vapor or gas between the area to one side of the metal 24 and that on the other.

It is important that the strip 24 be of metal in that such a material has been found to combine the special properties required herein. Thus, it will be impervious to vapor and gas, will be rigid, will not warp with time, or adverse conditions, and will retain its flexibility, thus insuring a good seal throughout its storage life.

A suitable backing 31 such as a display card or the like with a compatible coating thereon will be placed over the formed sheet of material 14 directly on the formed flanges 30 thereof. It will be sealed thereto by a well known process, such as heat sealing, laminating, gluing, or the like.

It will be noted then that the finished product, as shown most clearly in FIGS. 4 and 5, will accomplish all of the objects previously set forth and others. The decorative item with a scent impinged therein will be clearly and economically contained within ablister package on a display decorative item and the metal or metalized substance 24 at the back of the said decorative item 21, will prevent almost indefinitely the escape of the fragrance of scent.

This said metal 24 or other metalized substance is deemed to be an especially important feature of this invention. Ordinary backing boards of cardboard, paperboard, or the like, with-time allow the escape of the fragrance or odor and thus, destroy the elfectiveness of the unit.

Additionally, it has been found that the finished item,

when displayed as shown in FIGS. 4 and 5, will simulate the more decorative appearance of an item 21 packaged within a liquid.

Additionally, the reflective or mirror characteristics of the metal or metalized backing 24 will display the decorative item to best advantage.

While there are above disclosed but a limited number of embodiments of the structure and product of the invention herein presented, it is possible to produce still other embodiments without departing from the inventive concept herein disclosed and it is desired, therefore, that only such limitations be imposed on the appended claims as are stated therein or required by the prior art.

Having thus described my invention and illustrated itsuse, what I claim as new and desire to secure by Letters Patent is:

1. A display package for a scented novelty item, comprising:

(a) a formed bubble member, having an open side,

(b) said formed bubble member being adapted to receive a scented novelty item therewithin,
